Description
Summary:The aim of this work was to investigate the structural, electrical and electrochemical properties of Li4ZrxSi1-xO4 (0.02 ≤ x ≤ 0.06) compounds prepared via sol gel method. The X-ray Diffraction results showed that all compounds can be indexed to monoclinic structure in space group P21/m. The Li4Zr0.06Si0.94O4 compound showed highest bulk, grain boundary and total conductivity values of 1.19 × 10−4 S cm−1, 4.75 × 10−5 S cm−1 and 3.41 × 10−5 S cm−1 respectively. The insertion of Zr4+ is found to enhance conductivity of the parent sample Li4SiO4. Linear sweep voltammetry results showed that Li4Zr0.06Si0.94O4 ceramic electrolytes was electrochemically stable up to 5.07 V versus a Li+/Li+ reference electrode.
